We need more precise measurement because height difference is so large in volcanic field. In levelling survey, it is very important to examine the secular change of the rod constants under wide environmental conditions. We developed a measurement system to examine the rod constants using interferometer in 1993. The rod constants have been measured repeatedly since 1994 by using this system for our levelling staves. The unusual change of the graduation has not been detected until now since then. This measurement system is surveyed and examined in this paper. A circular bubble level is used to install the levelling staves vertically. We also achieved some improvements to this circular bubble level. We introduce briefly this result in this paper.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜総説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71741","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKEDA, Toyotaro"}]},{"nameIdentifiers":[{"nameIdentifier":"71742","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOYAMA, Etsuro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032195","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11602838","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute，University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学地震研究所技術部総合観測室"},{"subitem_text_value":"Technical Supporting Section for Observational Research, Earthquake Research Institute, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹田, 豊太郎"}],"nameIdentifiers":[{"nameIdentifier":"71739","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小山, 悦郎"}],"nameIdentifiers":[{"nameIdentifier":"71740","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"10_001-011.pdf","filesize":[{"value":"1.4MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"10_001-011.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32204/files/10_001-011.pdf"},"version_id":"7f3f580e-323f-4924-8583-a9207e10a18d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Levelling staff","subitem_subject_scheme":"Other"},{"subitem_subject":"Rod constants","subitem_subject_scheme":"Other"},{"subitem_subject":"Interferometer","subitem_subject_scheme":"Other"},{"subitem_subject":"Circular bubble level","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"水準標尺の定数とその測定について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水準標尺の定数とその測定について","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4479","4480"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32204","relation_version_is_last":true,"title":["水準標尺の定数とその測定について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:30:21.106754+00:00"}
